The analysis of the curves shows that the fibers arranged in the center of the yarn attain the most stretching and by approaching to its surface the stretching force under large values of the angle significantly reduces. Besides the distribution of the axial stress over the radius of the yarn is basically influenced by longitudinal Poisson ratio for the yarn. At the same time, the growth of this ratio results in the growth of stretching forces of the fibers in the center of the yarn.

Dear Sumit Bhowmick

Ceramic solidification crystallography is highly depends on melt cooling rate and the densification degree during melt rapid solidification process. The cooling rate values of the ceramics melt and subsequent rapid solidification are thermodynamically produce different structure: amorphous, nano-crystalline, cellular and dendrite crystal. The higher the cooling rate produce amorphous structure and the very low cooling rate produce dendrite crystals structure.

Now, in term of ceramic structure defect, the bulk integrity is related to the type of applied technique for melting and cooling. For instance, pores can readily form and deteriorated the properties of the bulk structure deposited by thermal spraying technique, while by thermal explosion spraying showed a high relative density and no pores. This integrity play role in the thermokinetic part of the phase growth. In this respect, the work by the Zhonghai Xu et.al, [1] titled " Microstructure Evolution and Model Analysis of Al2O3/ZrO2 Hypoeutectic Ceramic During Rapid Solidification" and later the work by the Jiayu Pan et.al,[ 2] titled" Solidification mechanism and microstructure evolution of Al2O3-ZrO2 ceramic coating prepared by combustion synthesis and thermal explosion spraying" are very interesting to look at.
